台湾岛南部海域温跃层个例特征分析

利用台湾岛南部海域若干观测点的水温垂直分布资料,计算了各研究个例的温跃层要素,并进行了较为详细的分析.结果表明：台湾岛南部海域春、夏、秋、冬均有温跃层存在,其中以多跃层为主,每一跃层厚度较小.太阳辐射的强弱会影响跃层的强度;大风、寒潮等灾害性天气对第 1层温跃层的深度影响较大,但对强度和厚度的影响不明显;海流因素会影响到第 1层温跃层的深度和强度;地形也可能是影响第 1层温跃层深度和强度的重要原因之一.分析结果对认识该海域海洋温跃层的分布特征可以提供有益的参考.

Characteristic analysis of thermocline samplesin south sea area of the Taiwan Island

With the vertical distribution data of temperature of some observation points in the south sea area of the Taiwan Island, the factors of the thermocline of the samples were computed, and then a particular analysis was made. The results indicated that there were thermoclines in the south sea area generally. All these thermoclines were almost multi-thermocline,and the thickness of every thermocline was small; The daily variety of the sun radiance had an effect on the depth and the intensity of the first layer thermocline. The effect of the disastrous weather such as gale and cold wave on the depth was very strong while on the intensity and thickness was not obvious. Ocean current had effect on the depth and the intensity of the first layer thermocline. Terrain also obviously affected the depth and the intensity of the first layer thermocline. The analysis results provide beneficial reference for deeper under standing of the distribution characteristics of the thermocline in this ocean area.
